The sizzling Barbados-born beauty lost her undies for this sexy shoot and it seems her rump was so scorching one of the photographer's assistants had to douse it in mineral water to bring her temperature plummeting back down to earth.

It was bottoms-up for Rihanna as she arched her back and gave the camera a seductive glance.

Posing in a teeny weeny ripped white vest, Ri was completely NAKED from the waist down.

Drake's girl seemed keen for the world and their wife to catch a cheeky peek of her white bits.

And boy did she deliver!

Thrusting her asset to the sky, the Disturbia songbird displayed some seriously mind-blowing curves.

It looks like the singer could have really done with an Umbrella…ella…ella to prevent the sun's scorching rays from pelting down on her delectable derrière.
